CAR COUPLING.

SPECIFICATION forming part of Letters Patent No. 307,774, dated November 11, 188%. Application filed April 14, 1884. (No model.)

To aZZ whom, it may concern.-

Be it known that I, OSMAN S. KING, a citizen of the United States, residing at Painesville, in the county of Lake and State of Ohio, have invented certain new and useful Improvements in Oar-Couplings, of which the following is a specification, reference being had thereinto the accompanying drawings, in which- Figure 1 is a perspective view of a drawhead with my improvement attached thereto. Fig. 2 is a top view of the same. Fig. 3 is a side view of the same. Fig. 4 is a perspective view of the adjustable sliding support for the link.

My invention relates to car-couplings; and

the objects of my improvement are to provide means for automatically holding the free end of the coupling-link at the proper angle to enter the draw-head of another car whatever may be the height thereof.

The invention will first be describedin connection with the drawings,and then be pointed out in the claims.

In the drawings, A represents a draw-head adapted to receive one end of the link B, that is retained connected with the draw-head by the vertical pin 0, passing through the holes a in the draw-head.

To retain the free end of the link at a proper angle for coupling with another draw-head there is secured to one side of the draw-head upon a pin, a an arm, D, that extends suflioiently forward of the draw-head to come in. contact with the under side or lip of another draw-head before the link has come in contact therewith.

To prevent the forward extremity of the arm D from striking against the face of the incoming draw-head said forward end is bent downward, so that the point of contact will be upon its curved upper edge, d.

To retain the arm D at the desired angle there is placed upon its pivot-pin a a spring, a", that may be of coiled wire; but I prefer rubber for the purpose, as it has more adhesive qualities, and the tension upon the spring can be regulated by a nut, a, placed upon the end of the bearing-pin a To keep the two ends of the arms D nearly balanced, and thus relieve the spring a of some of its tension, the inner end of said arm is weighted or provided with a weight, I), slightly less than the forward end of the arm. Said forward end may be madestraight out from the central portion of the arm, as shown in dotted lines, Fig. 2, in which case the opposite draw-head will have to be provided with a bracket, of, on one side, and the lower portion thereof, as shown also by dotted lines in Fig. 2; but I prefer to bend the arm inwardly at d and forward again, so that its free end will come directly in contact with the under side of the incoming draw-head. The portion of the arm D supporting the link B may extend across the front of the draw-head, as shown by dotted lines D in Fig. 2; but as car-links are not all of the same length it is desirable that the height of their projecting end should be adjustable upon the arm D, so that,whatever may be the point (on the upper edge, (I, of the arm) at which the incoming draw-head strikes, the link will be sure to enter within. I accomplish this by securing to the inner side of the arm D a metal strap, D", so that its upper face is below the edge (1 of the arm, and will not come in contact with the incoming draw-head; and upon said strap a sliding nut, c, is placed, havin g one end, 0, preferably bent upward to retain the car-link, and the other provided with an eye, 6 adapted to ride upon the strap D.

To keep the sliding rest where set upon the strap,whatevcr may be the incline of the arm D, a frictional spring,o", is secured to the rest 0 and made to bear against the side of the strap, the necessity of the spring 0" depending I upon the location of the pivot-pin a on the side of the draw-head and the incline of the arm I), and in some cases it may be dispensed with.

Theportion D of the arm maybe united to the bracket a and the latter be pivoted to the side of the draw-head.

Having now fully described my invention, I clai1n- I 1. A draw-head provided with a bent arm,

D, on one side thereof, a weight, D, upon the rear end of the arm, and a spring, (6, upon upon the pivot of the arm, strap D seouredto the pivot of said arm, substantially as and for the side of the arm, rest 6, and spring e subthe purpose described. stantia-lly as and for the purpose described.
